To all-whom imag/concern:

Be it known-.that I, WILLIAM KNICK- REHM, aicitizen of fthe United States, resid- 'inglat Somonauk, in .theycounty of Dekalb and State .of Illinois, have invented certain new and useful Improvements in Composite Railway-Ties; and I doydeclare the followingtobe fa full, clear, and exact description of .the invention, such as will enableothers skilled in the Iart to which itappertains to structure upon which the track rails Vare de- `signed to be placed.

With this .general object in View, my invention consists in the =novel`features lof construction, -combination and arrangement of parts which Twill ,hereinafter be more particularly described Vand vvclaimed and shown the drawing wherein: v

vFigure 1 represents aside elevation of one of my improved Aties, `portions thereof being in section; Fig. 12 is a detail plan View of fone Vend of this tie showing a `portion. of a .rail thereon;v Fig. 3 Vis la vertical section taken lon lthe plane of the line `33"of Fig. 1,; Fig. 4 is :a perspective v-iewof the reinlforcing frame; land Fig. 5 is asimilar view of the spacing bar.

My improved tie as covered Iby the present .application compri-ses a concrete body portion 1 in which an improved metallic frame structure is adapted to be embedded. This concrete body may be molded or pressed about the frame in any desired manner, it being merely essential .thatthe body portion present a general loutline of Ythe usual tie. This frame is formed of two laterally spaced .angle bars 2 substantially the length of the cross tie, said bars beingconnected by two pairs of cross bars 3 and 4. The pairs of cross bars 3 and 4 are spaced apart a distance equal to that which the track rails are spaced apart, and are also formed of angle bars such as compose the bars 2. The opposite ends of the vertical flanges 5 of these angle bars 3 and 4 are cut away to leave an upright flange which is of a length corresponding to the distance which it is desired to Space the bars 2 apart. The projecting `tion on top of the tie.

. ends 6 of the horizontal flange 7 of thebars 3 and aresecured by bolts or rivets or other fastenmg means 8 4to the upper side of the horizontal flanges of the bars 2 asbest disclosed in Figs. 3 and 4. The bars 3 and 4 are each spaced `apart a sulicient distance to readily receive cushioning elements 9, here shown in the formof substantially rectangular wooden blocks.

The blocks `9 are set in lU-shaped members l() which are positioned between the bars ,2 and have their upright flanges 11 secured to the inner faces of the vertical flanges of the cross bars 3 and 4. This construction Vallows the concrete to be `molded around the frame structure before placing the wooden blocks therein. In order to retain the blocks 9` within the U-shaped members 10, I provide substantially rectangular wear plates 12 which overlie said blocks 9 and the adjacent.

portions of the concrete portion of the tie. These wear plates 12 are spaced from the tie by means of additional cushioning members 13 also of wood, which act as deadening plates to prevent the unnecessary noise which would occur if the metallic wear plates were placed directly on the concrete tie. These cushioning elements 13 are of substantially the same size as the wear plates 12and havev openings 14 formed in their end portions which are adapted to aline with openings formed through the plates 12 for the reception of bolts 15 which serve to retain the plates 12 and 13 inoperative posi- These bolts 15 are here shown as four in number, one being used at each end of each of the plates, and are positioned between the bars 2. It is evident when the concrete is molded about Y the frame, these bolts will be securely held in position in the tie with their-threaded ends plates 12 and 13, a nut 16 being threaded upon each to securely clamp said plates in position. Additional openings 17 are formed in the metallic wear plates 12 for the reception of the usual spikes 18 used for securing the track rails R to the ties.

The innermost bolts 15 are connected by a spacing bar 19 which preferably underlies the concrete body portion 1 as shown in Fig. 1. While I have shown the spacing bar 19 as being outside of the concrete body portion, it is obvious that it may be molded within said body portion and serve the same purpose. This. bar not only acts as a spacing member but also materially strengthens the frame.

From the foregoing description taken in connection with the accompanying drawing, it is evident that I have produced a very simple yet improved form of reinforcing frame for concrete railway ties and one which will last indefinitely if the concrete is properly molded thereabout and it is also evident that when the wooden cushioning elements 9 and 13 become rotten or decayed, they may be replaced simply by removing the wear plates l2 when additional elements may. be inserted.

I claim as my invention:

l. A reinforcing fra-me for composite railway ties comprising a pair of laterally spaced angle bars, two pairs of spaced apart cross bars connecting said angle bars, said bars being spaced apart the distance the track rails are to be spaced, aU-shaped member having upright flanges secured between the spaced apart cross bars, a rail cushioning element disposed in each of Said U-shaped members, and means for holding said elements in operative position.

2. A reinforcing frame for composite railway ties comprising a pair of laterally spaced angle bars, two pairs of-spaced apart cross bars connecting said angle bars, said bars being spaced apart the distance the track rails are to be spaced, a U-shaped member having upright flanges secured between the spaced apart cross bars, a` rail cushioning element disposed in each of said U-shaped members, a wear plate disposed over each of said cushioning elements upon which the rails are'adapted to rest, and means for. securing said plates in operative position.

l 3. A reinforcing frame for composite railway ties comprising a pair of Vlaterally spaced angle bars, two pairs of spaced apart cross bars connecting said anglebars, said bars being spaced apart the distance the track rails are to be spaced, a U-shaped member having upright flanges secured between 'the spaced apartcross bars, a rail cushioning element disposed in each Vof said U- shaped members,a wear platejdisposed over each of said cushioning elements andadapted to overlie the adjacent portions of the pair of bolts.

cushioning element disposed in each of said. i U-shaped members, ya substantially rectangular wear plate disposed overeach of said cushioning elements and adapted to overlie the adjacent portion of the tie, an additional cushioning element interposed between each Y,

of said plates and the tie, and bolts adaptedV to eXtend between the pair ofr angle bars and through each end portion of the wear plates and thel last mentioned lcushioning elements.

5. A reinforcing Vframe for ,composite railway ties, lcomprising a pair of laterally spaced angle bars, two pairs of spacedapart cross bars connecting said angle bars, said bars being spaced apart the distance the track rails are tobe spaced, a U-shaped member having'upright lianges secured between the spaced apart cross b ars, a rail l cushioning elementdisposed in each of saidY U-shapedA members, a vsubstantially rectangular wear platedisposed over each of salad cushioning Velements andV adapted to overlie Vthe adjacent portion of the tie, an additionalk cushioning element interposed between each ofsaid plates and the tie, bolts adapted toV extend between the pairrof angle barsjand through each end portion of the wearlplates and the last mentioned cushioning elements, and a spacing bar connecting the innermost In testimony whereof I Vhave hereunto set my hand in presence of two subscribing witnesses. p Y y fj p p WILLIAM HENRY KNIGKREHM.
